Organic Fertilizer Production Process

  1. The ratio of raw materials per ton

500 kg of cow dung + 300 kg of duck manure + 200 kg of bacteria residue + 100 g of RW bacteria.

(The above cow dung and duck manure can be replaced by other livestock manure)


  1. The pile

According to the above ratio of raw materials, the piles are piled according to the needs. The length of the pile is not limited, the width is 2 meters and the height is 1 meter. When the pile is piled, it is necessary to stack the materials evenly layer by layer.


  1. Add bacteria

The bacterial agent is expanded by a ratio of 1:5, and after being uniformly mixed, it is sprinkled on the surface of the pile according to the number of piles.


  1. Stirring fermentation

Stir the strip pile evenly with a compost turner. After the temperature rises to 60 degrees or more, turn it over every 4-5 days, and ferment the mixture at 60 degrees or more for 15 days.


  1. Screening processing

According to the above steps, after fermentation, after sieving and deep processing, it becomes pure organic fertilizer.


  1. Granulation

The fermented pure organic fertilizer is granulated. The granulator, the disc granulator, the extrusion granulator, the extrusion and throwing machine, etc. are selected according to different raw materials.


  1. Drying, cooling, packaging

The freshly prepared granules have a relatively large moisture content, and the moisture needs to be dried to less than 20% of the organic fertilizer standard, and the dried granular organic fertilizer is directly packaged after being cooled by a cooling machine.
